Wow! Great memories of "Weird" on Channel 13, Houston, Saturday nights at 10:30. This was during the early through the late 1960s.The opening music was a creepy Theremin piece I can still whistle. An announcer would introduce the movie (just a voice over if Im not mistaken) and say "Weeeiiiirrrrdddd". I don't remember "Late Weird", but I was quite young and had to go to bed before that would have come on.
Some titles I remember -
Them, The Attack of the 50 Foot Woman, The Incredible Shrinking Man, The Thing, The Beginning of the End, The Blob, Caltiki, Attack of the Mushroom People, Day of the Triffids, and many many more...
Some were kinda Gothic horror movies from the 1930s and '50s, but most were 1950s drive-in fare.
Anything with atomic bomb induced mutations made the grade for "Weird".
Channel 13 had some great shows back then. Remember "Kitrick"?
